Comparison
Tokn vs 2FAS
2FAS is a polished, popular open source authenticator and one of the friendlier apps to switch to. The main philosophical difference: 2FAS offers cloud backups through Google Drive and a browser extension that talks to your phone, while Tokn keeps everything strictly on your device and your local network.

Where Tokn pulls ahead
Tokn never touches a cloud service. Backups are encrypted files you store wherever you want, and moving to a new phone happens directly between the two devices over local Wi-Fi, Wi-Fi Direct, or an animated QR code. Tokn also runs without Google Play Services, ships on F-Droid, organizes accounts into groups, and reads 2FAS backups directly, so switching is painless.
Where 2FAS has the edge
2FAS has an iOS app and a browser extension that approves logins from your phone, and neither has an equivalent in Tokn. If you need your authenticator on an iPhone too, or you want Google Drive backups for convenience, 2FAS is the better fit.
Bottom line
Both are honest open source apps. Pick 2FAS for the cross-platform extras. Pick Tokn if you want your 2FA strictly offline and your backups in your own hands.
FAQ
Common questions
Can Tokn import my 2FAS backup?
Yes. Export a backup in 2FAS, open the import screen in Tokn, and pick the file. Your accounts come across in one step.
Is there an iOS version of Tokn?
No, Tokn is Android only. If you need an open source authenticator on iOS, 2FAS or Ente Auth are solid choices there.
Does Tokn have a browser extension?
No, deliberately. Tokn keeps your codes in one encrypted vault on one device. You type the code when you log in, and nothing else has access to your secrets.
